and do not contain Ammonites and Belemnites ; in which respects 

 they cannot be compared with the deposits of Sonthofen, &c. Out 

 of more than 100 species of fossils collected from Gosau, there are 

 from SO to 40 species of bivalves, and of those capable of being iden- 

 tified, about equal numbers are referrible to the youngest secondary 

 and the oldest tertiary formations. 



The univalves are much more numerous than the bivalves, espe- 

 cially in the quantity of each species, a fact never observed in any de- 

 posit of secondary age. Amongst upwards of 50 species of univalves 

 which the authors collected, three only are found in the chalk and 

 green-sand, whilst 7 species are identical with known tertiary fossils j 

 and several of the genera, such as Volvaria, Pleurotoma, and Voluta, 

 they conceive have never been seen in any secondary formation. 



In confirmation of their views, the authors refer to the catalogue 

 of the Kressenberg fossils published by Count Miinster, with whose 

 opinions they coincide. They also refer to the lists of fossils found 

 in the beds over the chalk near Maestricht, and they conclude that 

 the deposit of Gosau, like that at Maestricht, forms one of the 

 terms of a new series, younger than the chalk, and to be interpo- 

 lated between that formation and the calcaire grossier. 



The abstracts of the papers on the Tertiary Formations of Austria 

 and Bavaria, published in the Phil. Mag. and Annals of Philosophy, 

 for January 1830, were necessarily incomplete, and in some respects 

 erroneous, owing to the detention at Paris of nearly all the fossils 

 collected by the authors. This memoir contains the opinions of the 

 authors, after a careful revision of all the facts, on which their con- 

 clusions are founded. 



June 4. — Rev. Richard Dawes, M.A., Fellow and Tutor of Down- 

 ing College, Cambridge; Rev. Charles Currie, M.A. Fellow of Pem- 

 broke College, Cambridge; Rev. Thomas Musgrave, M.A. Fellow 

 of Trinity College, Cambridge; William Devonshire Saull, Esq. of 

 Aldersgate Street, London ; and Francis Ellis, Esq. of the Royal 

 Crescent, Bath, — were elected Fellows of this Society. 



A paper was read, entitled " On the Geological Relations of the 

 South of Ireland, by ThomasWeaver, Esq. F.G.S. F.R.S. M.RJ.A., 

 &c." 



This Memoir gives an outline of the mineral constitution of a 

 large tract in the south of Ireland, comprising the counties of Cork, 

 Kerry, and Clare, with part of those of Galway, Tipperary, and 

 Waterford; and thus connecting this portion of the island with the 

 eastern part of it, formerly described by the author. 



This hilly and diversified region is chiefly composed of ridges, 

 having generally a direction from east to west, and attaining their 

 greatest elevation in the mountains of Kerry, where Gurrane Tual, 

 one of Magillycuddy's Reeks, near Killarney (the highest land in 

 Ireland), is 3410 feet above the sea. 



The rocks in this elevated country are chiefly of the transition 

 class : they decline gradually towards the north, and finally pass 

 under the old red sandstone and carboniferous limestone of the 

 midland counties.
